On the revi.pdf file pg. 5 shows something of a 12/d. I am looking for any info on the size of the reticule/image on the gunsight. This includes the hash marks and all. Basically looking for anything on the gunsight size and what each hash mark represents. It maybe called optics in german, not sure.

I try to translate page 5 of the revi.pdf:
Identification: The Revi C/12 D is an optical visor device, that is used for fixed guns in an airplane. It can also be used for dive bombing.
Technical Details
[/i]
Equipment system:
Reflex visor with mechanical adjustment and darkening resistance
Optical values:
Visual field (range of vision)............13°
Exit pupil........................ .............50 mm Ř <- (!) I guess this is the diameter of the circle of the reticule
Eye distance to reflex glass............200 mm to 450 mm
Optical visor line:
shining crosshair with predicted position circle: 10% of the target distance (e.g. 10 meter by target distance of 100 meter)
Mechanic visor line:
Mechanical back-up visor with target thorn and circular...(?)Then you can read something about the adjustment range, electrical specifications, and the size of the 12/d.
Not much infos about on the size of the reticule/image on the gunsight. All I (!) found that might help you is the above image I send yesterday. There you can see the reticule/image. The size of the 12/d is as following: length 220 mm / width 103 mm / height 170 mm. This infos and the above image might help to figure out the size/diameter of the reticule...5 cm (?) (100 mm = 10 cm)
I hope this helps.
